Blood Orange Tree

‘Moro’ is an early-ripening blood orange with a round, spreading tree and fruit whose flesh develops a deep red color. Cool winter weather encourages stronger pigmentation, while warm inland conditions support the best color and flavor, as described by [UCR’s Citrus Variety Collection](https://citrusvariety.ucr.edu/crc3811) and [UF/IFAS Extension](https://ask.ifas.ufl.edu/publication/HS1500). ## Fruit and form The medium-sized fruit has orange peel that may develop a burgundy blush and juicy flesh with few seeds. Moro ripens early among blood oranges; UCR records December to February ripeness at Riverside. A commercial Moro profile also records fragrant white flowers and evergreen foliage ([SiteOne](https://www.siteone.com/en/79483b-citrus-sinensis-moro-blood-orange/p/573637)). ## Siting Give the tree full sun for fruit production and color. Blood oranges need well-drained soil and regular moisture during fruit development. In mild-winter climates, fruit may remain less pigmented even when ripe; young trees can be damaged by temperatures below 25°F, according to UF/IFAS. ## Maintenance Water deeply when the root zone begins to dry, especially during establishment and fruit growth. Keep the planting area free-draining, and prune selectively after harvest to remove dead or crossing branches and maintain access for picking. Protect young trees during hard freezes.
